4.6.10 QSC function (sensor quality control)
The QSC function (Quality Sensor Control) is a new sensor evaluation
for digital IDS sensors. It evaluates the condition of an IDS pH sensor
individually and with a very fine grading.
On the display, the QSC color scale (from green to yellow) indicates the
current sensor evaluation by means of a pointer.

Info
The sensor evaluation is documented as a percentage (1 - 100) both in
the calibration record and for individual measurement datasets.
The finely graded sensor evaluation of the QSC function promptly calls
your attention to changes of the sensor.
Thus you can do what is necessary to restore the optimum measuring
quality (e.g. clean, calibrate or replace the sensor).
With QSC function
Very fine grading of the sensor
evaluation (100 grades)
The reference value is individu-
ally determined for each sensor
during the QSC initial calibra-
tion.
Low tolerances for zero point
and slope when using QSC buf-
fer solutions
Additional QSC calibration
required (with special QSC buf-
fer set)
QSC color scale
The double arrow on
the color scale indi-
cates the current sen-
sor evaluation.
Without QSC function (sensor
symbol)
Rough grading of the sensor
evaluation (4 grades)
A theoretical reference value is
used for all sensors
Greater tolerances for zero point
and slope when using commer-
cial buffer sets
No additional calibration required
